The long-established activities of the department of Life Cycle Engineering (LCE) induce 200 person years of outstanding experience in developing Life Cycle Assessment methodology, software (GaBi) and databases (eco-profiles). The department provides services in Life Cycle Engineering, including Life Cycle Assessment (LCA), Design for Environment (DfE), Energy Efficiency benchmarks and Material Flow Analysis (MFA). It plays an important part in different SETAC working groups, and is represented in the international UNEP/SETAC Life Cycle Initiative for fostering LCA capability, harmonization and database-access worldwide. In addition to that, IBP LCE develops and applies methods in cooperation with industrial clients as well as governmental institutions on national and international level.
